Description
Positive output voltage
Neqative output voltaqe
Turns the output to On and Off by electrical signal or dry contact between pin 6
and pin 11 (Signal Return). 0-0.6Vor Short: On, 2-15Vor Open: Off.
The maximum sink current is 2.6mA
Positive sensing. The +Sense signal should be connected to the positive
terminal of the load. The +Sense and -Sense leads should be twisted pair to
minimize noise pick-up effect. The maximum load wires drop compensation is 1V/wire
Open collector signal, referenced to pin 11 (Signal Return). On when Vout ≥80%+/-5%
The maximum sink current is 10mA and the maximum external voltage is 15V.
Return for the following control and supervisory signals: On/Off, DC_OK,
Over_temperature Alarm, AC_Fail, Auxiliary 12V supply. The Signal return is
isolated from the output terminals.
Open collector signal, referenced to pin 11 (Signal Return). On when the input
voltage is ≥85Vrms. The maximum sink current is 10mA and the maximum
external voltage is 15Vdc.
Open collector signal, referenced to pin 11 (Signal Return). On when the internal
temperature is within safe limit, Off approx. 10°C below Thermal shut down. The
maximum sink current is 10mA and the maximum external voltage is 15V.
Negative sensing. The -S signal should be connected to the negative terminal of
the load. The -S and +S leads should be twisted pair to minimize noise pick-up
effect. The maximum load wires drop compensation is 1 V/wire.
Current sharing signal. When units are connected in parallel, the CS pins of the
units should be connected to allow current balance between units.
Auxiliary voltage output, 11.2-12.5V. referenced to pin 11 (Signal Return). The
maximum load current is 0.25A. This output has built in Oring diode and is not
controlled by the On/Off control.
Descriotion
